extension rod tools and method of using the tools for allowing power tools such as power drills and power screw drivers and socket wrenches to be able to open and/or close crank handles on windows and/or shutters. The novel tools can have flat sided ends that can attach to the power tools or socket wrenches, and have second opposite ends that fit over a raised t-shaped pin on the crank handle to the window/shutter. The second end of the rod tools can have a pair of opposite located slots that lock onto the t-shaped pins so that twisting the rod tools locks the rod tools to the crank handle.

This invention relates to windows and storm shutters and in particular to an extension rod tool devices and methods of use to allow power tools and socket wrenches to automatically open a close existing elevated window type shutters that have T shaped and crossed pins in their crank knob.
Elevated window and storm shutters are known to have built in shutter cranks that require long extended hand crank arms, that require a user to grip the shutter crank, and manually rotate the long extended arm to open and close the shutters. The manual action can be both tedious, time consuming, and difficult to most users. As a result, often the hand crank arms are not used, and the shutters remain in either constantly open or closed positions.
Various tools have been proposed over the years that can be attached to and be used for extending the reach of power tools. See for example, U.S. Pat. No. 1,765,362 to Berry; U.S. Pat. No. 3,011,813 to Arneson; U.S. Pat. No. 4,357,845 to Cornia; Des. 358,082 to Trezza; U.S. Pat. No. 6,171,033 to Wrobel; U.S. Pat. No. 6,382,885 to Isaksson; and U.S. Pat. No. 6,558,089 to DeBlasio. However, none of these devices has been described for use with crank arms on shutters and windows. In addition, these patented devices would not be able to be used with T-shaped control knobs used on elevated shutter type windows.
U.S. Pat. No. 4,984,489 to Krauthamer describes a “window handle turning accessory”, title, that can attach to a power drill. However, this device requires an enlarged cylindrical housing with a rear conical section that is separately attached to a smaller diameter shank, the latter of which is attached to the power tool,
The Krauthamer accessories would require the user loosely fit the enlarged heads of the accessory over the knobs without locking the knob to the accessory. Thus, the Krauthamer accessories can potentially disengage and fall off the knobs during use.
Furthermore, the Krauthamer accessories would not be practical or easy or inexpensive to manufacture due to the enlarged head which must require separate machining and molding before it can be attached to a shank for use with a power tool.
In addition, the Krauthamer accessories would not be able to be used with cross positioned and T-shaped pins that are used on cranks of elevated window shutters since their heads would not fit thereon, and would not be able to lock onto T-shaped pins on the cranks of elevated window shutters. Furthermore, the short shank lengths in the Krauthamer accessories are not long enough to be used with elevated shutter windows.
Thus, the need exists for solutions to the problems with the prior art.
A primary objective of the present invention is to provide an extension rod tool and method of using the extension rod tool with power drills and power screw drivers, that can automatically crank open and crank closed an elevated window type shutter having a crank handle having cross shaped and T-shaped pins.
A secondary objective of the present invention is to provide an extension rod tool and method of using the extension rod tool with power drills and power screw drivers, that can automatically lock onto and easily be released from crank handles having cross shaped and T-shaped pins used on elevated window type shutters.
A third objective of the present invention is to provide an extension rod tool and method of using the extension rod tool with elevated window type shutters having a crank handle having cross shaped and T-shaped pins, that is inexpensive to manufacture and use.
Embodiments of the invention can include novel rod shaped members having a flat sided end such as a hexagon shaped perimeter end that can be inserted into an adjustable chuck head of a conventional power tool(battery, cordless or powercord), such as a electric drill, electric screw driver, and the like. The opposite end of the novel rod shaped member can include an adapter head end having an opening with opposite facing slit slots so that the adapter end can fit over a tip of a window/shutter crank handle and existing sideway protruding pins on the crank handle can pass through the side slits and lock into curved slots by rotating the rod shaped member.
A first embodiment can have a pair of clockwise oriented curved slots on opposite sides of the rod shaped member having a lower case b-shaped configuration. Twisting the rod counter-clockwise locks the rod to the crank handle.
A second embodiment can have a pair of counter-clockwise oriented curved slots on opposite sides of the rod shaped member having a backward lower case b-shaped configuration. Twisting the rod clockwise locks the rod to the crank handle.
A third embodiment can have a pair of t-shaped curved slots on opposite sides of the rod shaped member. Twisting the rod either clockwise or counter clockwise locks the rod to the crank handle.
A fourth embodiment can have a pair of oval shaped curved slots on opposite sides of the rod shaped member. Twisting the rod either clockwise or counter clockwise locks the rod to the crank handle.
The rod members can be easily removed by slightly twisting the rod members and pulling the rod members from the crank handle.
Further objects and advantages of this invention will be apparent from the following detailed description of the presently preferred embodiments which are illustrated schematically in the accompanying drawings.
Before explaining the disclosed embodiments of the present invention in detail it is to be understood that the invention is not limited in its applications to the details of the particular arrangements shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

Next, opening 125 of end 120 of extension rod 100 can be moved in the direction of arrow 12 to slip over tip portion 78 of crank handle 70 and allow pins 76 to pass through the vertical slot cut-out portions 122, 126 in the end 120 of the rod 100 until the pins 76 abut against a wall portion in the horizontal slot cut-out portions 124, 128. The extension rod 100 is then locked to the pins 76 of the crank handle 70 by twisting the extension rod in a clockwise direction as shown by arrow R2 until the pins 76 abut against another wall portion in the slots. A user can then turn on the power tool 50 to rotate in a clockwise direction allowing the shaft 74 of the crank handle 70 to close the shutter/window 60(shown in
